I get the following error message: After Effects Warning: Could not rename the file '/Users/jonahlee/Library?Preferences/Adobe/After Effects/10.0/Worspaces.9216.1407350837851841.xml' to workspaces.xml'.

The strange thing is that the file does not seem to exist. I even checked that directory with the terminal. I have run permissions and restarted, and I am still getting this message. Anyone hae any ideas.

My computer is a MacPro 2 x 2.26 GHz Quad-Core Interl Xeon with 16 GB of 1066 MHz DDR3 Ram running 10.6.3 so that should not be an issue.

I have restarted 3 times, and fixed permission 3 times and that has not helped.

I tried running it with Psuedo, so it is runnign with root permissions, and I got the error that the dynamiclinkmanager quite unexpectedle, and it gave me an error message about quicktime not being installed on the system, but seemed to boot anyway.

Thanks. Actually the file it was saying did not exist, but I trashed the whole folder for 10 and then it booted, except for this error message about quicktime again, which is installed. And because of this, it basically does not function, because it won't open any Quicktime video.

Todd - good to see you're posting here on a Sunday! Thank you. I started a similar thread on this forum titled CS5 Errors: QuickTime not installed.

I'm having the same issues on may laptop, though not on my Mac Pro desktop. Both machines have 10.5.8 with QuickTime Pro 7.6.4 installed.

On the laptop I logged in as another user and the issue is gone. Not an acceptable solution for me however.

I updated to 10.6.3 (with QT 7) and this did not resolve the issue.

After Effects took 4 minutes to launch showing "Initializing Media Core", then reported that QT was not installed, then reporting that Output Modules are missing, then complaining that it cannot write the xml file before finally crashing.

I manually set the read/write permissions to all folders and files inside the user/Library/Preferences/Adobe/After Effects/10.0 directory to read and write for Everyone. I also created a Workspaces.xml file, this got me through the launch sequence.

However it still reports that QT is not installed. This is now on 10.6.3 with both QT X and QT 7.6.6 Pro installed.

When I look at the output module templates most are missing, even RAM Preview is unavailable, presumably since it uses QuickTime on the Mac.

Looks like Premiere Pro CS5 is also affected, just tried to launch Premiere and its hung (now 4 minutes and counting) at "LoadingImportQuickTime.bundle".

I have the CS5 Master Collection and rarely use Premiere but it must use the same 32 to 64 bit interpretation of QT to make it work.

Update: Premiere launched after 7 minutes. All appeared normal until I imported a QuickTime file (one of the free Artbeats clips). I got an error message reading "The file has no audio or video streams." Cool :/

The "QuickTime Isn't Installed" error after the long delay "Initializing Mediacore" is almost certainly a result of attempting to launch when a zombie version of "Adobe QT32 Server" is left running as a result of some other crash or launch failure.

It can easily be remedied by either quitting that process in Activity Monitor or by rebooting, and then re-launching AE.

I was having the same issue. I deleted the Workspace.xml and everything started as usual. I am using 2 monitors and I'm wondering if that may have something to do with it... The default workspace I had set up spanned across both monitors...

Solved – yeah! I was having this trouble too (I'm Mac Pro, SnowLeopard, AE CS5, AE failed to find Quicktime with my regular user, but worked fine with alternate user account) and mograph_bc ( post 9 ) suggestion for — 'removing all Preferences from the Adobe directory except the After Effects Prefs' — is what FINALLY worked for me, after ~12 hours of Adobe forums research, various repeated failed attempts on my own and several hours of live adobe tech support had not resolved the issue. Adobe gave up before I did, then I found this : ) worked!
